The Falas only occasionally enters into the events of the First Age; in the First Battle of Beleriand, Morgoth's host overran the Falas and besieged the two havens, but lifted the siege in order to join in the Second Battle. The Havens of the Falas were finally destroyed in F.A. 473, and Círdan's people fled to the Mouths of Sirion and the Isle of Balar.
